Benefits

Saves Time

Easy to Install and Simple to Operate
Does not require programming or commissioning

Up and running in less than 10 minutes.

Motors Last Longer

Proprietary CL Software

Provides overload protection, prevents motor burnout
and eliminates nuisance tripping.
UL approved as electronic overload protector for motors.

Energy Saving

Uses only the power the application requires

Energy savings is realized by using variable motor speed
vs. constant speed motors.

Economical to Use: Indoors or Out

Eliminates secondary enclosure

No holes to drill, no switches to install.
No need to derate drive for high starting torque applications.

Combines Soft Start with Variable Speed

Adjustable Soft Start.

KB Customization for OEM’s

“You get exactly what you need. Nothing more, Nothing less.”

Includes: custom label, preset calibration, installing drive options and custom software.
Ready to use out of the box.

GFCI software* allows equipment to operate with Ground Fault Circuit Interruption circuit breakers or outlets.

*With factory programming.

Additional Features

Sensorless Flux Vector Control

Flux Vector Compensation with Static Auto-Tune provides excellent speed regulation
with high torque loads throughout the entire speed range. Auto energy saving at light
loads. Smooth motor torque.

Electronic Inrush Current Limit (EICL™) Protection

Eliminates harmful inrush AC line current during power up.

Run/Fault Relay Output Contacts

Can be used to turn equipment on or off, to signal a warning if the drive is put into
“Stop” mode, or to signal if a fault has occurred

.

Start/Stop Switch

Provides electronic “Start” and “Stop” functions.

Ride-Through

Provides smooth recovery to the previous set speed during a momentary power loss.

Holding Torque at Zero Speed

Resists motor shaft rotation when the drive is in “Stop” mode.

Regeneration Protection

Eliminates tripping due to high bus voltage caused by rapid deceleration of high
inertial loads.

Undervoltage and Overvoltage Protection

Shuts down the drive if the AC line input voltage goes above or below
the operating range.

Short Circuit Protection

Shuts down the drive if a short circuit occurs at the motor (phase-to-phase).

Basic, Programmable, Trimpot Adjustments

Min. Speed, Max. Speed, Accel, Decel, Current Limit, Slip Comp.

Drive Options

On/Off AC Line Switch

Disconnects the AC line.

Forward-Stop-Reverse Switch

Provides motor reversing and stop functions.

Signal Isolator

Provides isolation between a non-isolated signal source and the drive.

Auto/Manual Switch

When used with the Signal Isolator, it selects the remote process signal
or the Main Speed Potentiometer.

Class “A” (CE) RFI Filter

Installs inside the drive.

Liquidtight Fittings

Provides a liquid-tight seal for wiring the drive. Kit includes necessary
liquid-tight ttings.
